Router settings, firmware updates, or changes to the Wi‑Fi password can be performed through the configuration webpage or dedicated app provided by the router manufacturer. For more information, please refer to the router’s user manual or contact the manufacturer.
※ After changing the router settings, you may need to remove the saved network from devices that were previously connected to the network. When the devices reconnect, the router’s new settings will be applied.
It is recommended to assign different network names to the 2.4GHz, 5GHz, and 6GHz bands.
An SSID (Service Set Identifier) is the name used to identify a network. Devices searching for Wi‑Fi networks recognize available networks by their SSIDs, which are displayed in the Wi‑Fi network list.
Please ensure that each frequency band supported by the routers connected to the network uses a unique SSID. It is recommended to configure separate SSIDs for the 2.4GHz, 5GHz, and 6GHz bands.
If the same SSID is used across all bands, the router’s operating channel may change dynamically during product use after connection, which can result in unstable connectivity.
Example: After registering the product in the ThinQ app, the product may suddenly appear offline, or the DAFC connection may be disconnected.
A table showing supported frequencies by playback mode
※ Non DFS : 36/40/44/48/149/153/157/161ch.
※ Note: 6GHz support will be added through a future software update.
* Dolby Atmos FlexConnect (DAFC) & Stereo Pairing: DFS Not Supported
Features that require device‑to‑device communication—such as DAFC mode or Stereo pairing (two-speaker pairing)—do not support DFS channels to ensure stable wireless performance.
Therefore, these features must be used while connected to the router’s non‑DFS 5GHz channels (36 / 40 / 44 / 48 / 149 / 153 / 157 / 161).
* Standalone Speaker, AirPlay, Google Cast: DFS Supported
When using the speaker in standalone mode, or when streaming audio via AirPlay or Google Cast, DFS channels are fully supported.
If the routers are not configured to operate in Mesh or Repeater mode, it is recommended to assign a different SSID to each router installed in the home.
When multiple networks share the same SSID, devices are more likely to detect and connect to a different network with the same name. In such cases, the device with the ThinQ app installed (such as a smartphone or tablet) may automatically attempt to connect to a router different from the one the product is connected to. As a result, if the product and the mobile device are connected to different routers, the product may appear offline in the ThinQ app.

What is the “Digital Sound Out” setting on a TV?
“Digital Sound Out” is a function used when the TV is connected to an external audio device (such as via ARC or eARC).
It allows you to set the audio output format that the TV sends to the connected audio device.
Available settings are:
PCM
Auto
Passthrough
(Default setting: Auto)
Please refer to your TV’s manual for details on audio output formats.
When connecting a TV to the M7 or M5 via DAFC (wireless), do I need to change the TV’s Digital Sound Out settings?
No, you do not need to change any settings.
When the TV and M7 are connected wirelessly using DAFC, this connection path does not use the Digital Sound Out function.
Therefore, the Digital Sound Out menu becomes automatically disabled, and users cannot modify it.
This does not affect sound quality or functionality.
For a TV–H7 (eARC)–M7 or M5 (DAFC) configuration, which Digital Sound Out setting is recommended?
It is recommended to use Auto or Passthrough.
With these settings, the TV can send multichannel and Dolby Atmos audio signals to the H7 via eARC, allowing the H7 and M7/M5 speakers to work together to produce optimal immersive sound.
The two options are mostly similar, but differ in the following ways:
∙ Differences between Auto and Passthrough
- Auto:
Mixes in TV sound effects
(e.g., Audio Guidance, system notification sounds)
- Passthrough:
Sends only the original audio signal with no added effects
In the H7–M7 or M5 DAFC configuration, Passthrough can reduce audio latency slightly, making it recommended for content like sports.
PCM is not recommended
Selecting PCM limits the TV→H7 output to 2‑channel PCM, which significantly reduces immersive audio performance.
What Wi‑Fi bands are supported when connecting the product to a router?
Current Sound Suite products (H7 / M7 / M5 / W7) support 2.4GHz and 5GHz Wi‑Fi bands only.
※ 6GHz (Wi‑Fi 6E) is not supported yet. 6GHz support is planned via a future software update.
If your mobile device is connected to a 6GHz network during product registration in the ThinQ App, a message will appear asking you to “switch to another network.” In this case, switch your mobile device to 2.4GHz or 5GHz and proceed with registration.
※ 5GHz is recommended.
After the product has been successfully connected to 2.4GHz or 5GHz, your mobile device may reconnect to 6GHz, and product control will still work, as long as the smartphone and product are connected to the same router.
※ Note: 6GHz support is planned via a future software update.
After changing the router: reconnection required via the ThinQ App
Please follow the steps below to reconnect the product to the new network using the ThinQ App:
1) Turn on the product → ensure the LEDs/displays show normal status.
2) Turn off the old router.
3) Connect your smartphone to the new router’s 2.4GHz or 5GHz network.
4) Open the ThinQ App → the product card will appear offline.
Tap the offline product card → Settings → Change Network
Follow the app instructions to update the SSID and password.
Why is the connection unstable even though the signal is strong on a multi‑band router (2.4G/5G or 2.4G/5G/6G)?
Even with a strong signal, if the router has features such as:
Band Steering
Smart Connect
Unified SSID across multiple bands
enabled, devices may automatically switch between 2.4G ↔ 5G ↔ 6G, between nodes, or between channels.
This can cause the following issues:
∙ Only 1–2 devices connect when powered on; others fail to connect
∙ The connected devices change every time
∙ Intermittent dropouts/latency when forming or using a DAFC group
Recommended settings in this case
∙ Router settings
- Turn OFF Band Steering / Smart Connect / Unified SSID
- Separate SSIDs for each band (e.g., Home_24, Home_5G, Home_6G)
∙ Product / Mobile settings
- Connect H7 / M7 / M5 / W7 / TV all to the same SSID and same band (5GHz non‑DFS channels recommended)
Can I use DFS channels (5GHz DFS)?
Depending on the Wi‑Fi frequency channel settings of your router, the supported scenarios differ. For the most stable performance of various Sound Suite features, we recommend connecting to the non‑DFS 5GHz channels.
* (Table) Supported Frequencies by Playback Mode
※ Non DFS : 36/40/44/48/149/153/157/161ch.
※ Note: 6GHz support will be added through a future software update.
* Dolby Atmos FlexConnect (DAFC) & Stereo Pairing: DFS Not Supported
Features that require device‑to‑device communication—such as DAFC mode or Stereo pairing (two-speaker pairing)—do not support DFS channels to ensure stable wireless performance.
Therefore, these features must be used while connected to the router’s non‑DFS 5GHz channels (36 / 40 / 44 / 48 / 149 / 153 / 157 / 161).
* Standalone Speaker, AirPlay, Google Cast: DFS Supported
When using the speaker in standalone mode, or when streaming audio via AirPlay or Google Cast, DFS channels are fully supported.
If the product cannot connect to Wi‑Fi, try the following steps.
∙ Restart the router and try again.
∙ Set the router’s Wi‑Fi to 2.4GHz or a standard 5GHz channel (36/40/44/48/149/153/157/161).
∙ If your router has Band Steering, Smart Connect, Unified SSID, or MLO (Multi‑Link Operation) enabled, turn these features OFF.
∙ Separate the 2.4G / 5G / 6G bands into individual SSIDs (e.g., Home_24, Home_5G, Home_6G).
∙ If the router is using a Hidden SSID setting, disable it.
∙ Reset the product (refer to the manual for the reset procedure).
∙ Reconnect the device to the network using the ThinQ App.
∙ Ensure that your smartphone and the product are connected to the same router..

I would like to know which LG TV models support Dolby Atmos FlexConnect (DAFC).
Here’s the current list of LG TVs that support Dolby Atmos FlexConnect:
∙ 2025 Model Info. - OLED G5, C5, CS5
Planned update in the second half of 2026 : OLED CS5, QNED 9M
∙ 2026 Model Info. - OLED W6, G6, C6,
Planned update in the second half of 2026 : OLED CS6, B6, B6E, MRGB95, MRGB9M, MRGB85, QNED85, QNED82
Can Dolby Atmos be achieved using only four M7 or M5 speakers with a DAFC‑supported TV?
Even if your LG TV doesn’t support Dolby Atmos FlexConnect, or if you’re using a TV from another brand, you can still experience FlexConnect with the LG Sound Suite H7 together with the M7 or M5 speakers.
By connecting the H7 to your TV via HDMI ARC, the H7 can serve as the FlexConnect main device and pair with the M7 or M5 speakers. This allows you to build out a more immersive, expanded spatial audio setup.
If my TV does not support Dolby Atmos FlexConnect (DAFC), does that mean I cannot use DAFC with LG Sound Suite?
Even if your LG TV doesn’t support Dolby Atmos FlexConnect, or if you’re using a TV from another brand, you can still experience FlexConnect with the LG Sound Suite H7 together with the M7 or M5 speakers.
By connecting the H7 to your TV via HDMI ARC, the H7 can serve as the FlexConnect main device and pair with the M7 or M5 speakers. This allows you to build out a more immersive, expanded spatial audio setup.
Does Dolby Atmos work with only two M7 speakers?
Yes! With a Dolby Atmos FlexConnect supported TV, just two M7 speakers will give you Dolby Atmos playback. No soundbar needed for that setup.
When using Dolby Atmos FlexConnect (DAFC) with the Sound Suite H7, does the H7 need to be connected to the TV with HDMI?
Yes — the H7 needs to be connected to the TV via HDMI (ARC/eARC) when used in a Dolby Atmos FlexConnect setup. In this configuration, the H7 acts as the FlexConnect hub, while the M7 or M5 speakers connect wirelessly to the H7!
So while the speakers connect wirelessly within the system, the H7 itself still requires an HDMI connection to the TV.
When connecting an LG TV with LG Sound Suite, can DAFC and Wow Orchestra be used at the same time?
When a DAFC-supported TV like the G5 is paired directly with M7 speakers via FlexConnect, both the TV and the M7s work together to create the optimal sound.
If you’re running DAFC with the H7 as the leader, the TV speakers won’t output sound. In that setup, the H7 and M7 speakers handle the channel roles and work together to deliver the full audio experience.
Can I install two M7/M5 speakers as rear speakers and place two more beside the soundbar?
Yes, that setup is possible! You can place two M7 speakers behind the listening position and use the M5 speakers to the left and right of the soundbar. Dolby Atmos FlexConnect is designed to support flexible speaker placement, and the system will automatically optimize the audio based on the position of the connected speakers using DAFC.
The Sound Suite products connected to Wi‑Fi appear offline in the ThinQ App. Why?
There are two main reasons why products may appear offline.
Case1) More than one router in the home uses the same SSID
If there are two or more routers broadcasting the same SSID, your smartphone may connect to a different router than the one your Sound Suite product is registered to.
In this situation, the product may appear offline in the app.
To control the product, your smartphone must be connected to the same router as the Sound Suite device.
Recommended action
Separate the SSIDs of your routers (recommended).
Set different SSIDs such as: Home_Main / Home_Ext
Please ensure that both the smartphone and the product connect to the correct, same SSID.
Case2) Weak Wi‑Fi signal
If Wi‑Fi signal strength is low, the product may appear offline.
Recommended action
Place the router closer to both the smartphone and the Sound Suite device so that both connect to the same router with the strongest signal.
If the issue persists: Reset the network settings.
Recommended steps
Please move your smartphone closer to the router you want to connect to the Sound Suite device.
Turn Wi‑Fi off and on again on your smartphone.
The smartphone will reconnect to the correct router automatically.
Does the LG Sound Suite H7 support DTS?
Unfortunately, the LG Sound Suite H7 doesn’t support DTS, but if you have a DTS-supporting TV you can output the audio signal as PCM to the soundbar. However, if your TV supports DTS and can output the audio signal as PCM to the soundbar, you can still play DTS content that way.
Can the LG Sound Suite M7/M5 be connected to a computer?
The LG Sound Suite M7 and M5 support USB Audio (UAC 2.0). By connecting your computer to the M7 or M5 via a USB cable, you can play audio at up to 24-bit / 96kHz quality.
For an even fuller sound, you can wirelessly pair two identical M7 or M5 speakers in stereo mode. In that setup, simply connect the “master” speaker to your computer via USB, and you’ll get a richer stereo listening experience.
The LG Sound Suite H7, M7, and M5 all support Bluetooth, so you can also connect them to a laptop wirelessly if you prefer!
Does the LG Sound Suite H7 support wall‑mounting?

Are there dedicated stands for the LG Sound Suite?
The stands for the LG Sound Suite M7 and M5 are planned to go on sale starting around April 2026, but please note that availability timing may vary by country!
When ordering LG Sound Suite, can I choose any speaker combination I want?
Yes, there are multiple configurations that are possible as the LG sound suite is based on modular expansion. So you can start with a H7 soundbar or M5/M7 surround speaker, and later expand it based on your needs!
What is the difference between the LG Sound Suite M7 and M5?
While both models support DAFC, Room Calibration Pro, and AI Sound Pro, their hardware configurations differ:
M7: Features a woofer and 3 full-range speakers for a more immersive sound. It can support DAFC with just one unit.
M5: A compact yet dynamic model featuring a woofer and dual tweeters. To achieve full DAFC functionality, two units are required
